Hi ! Thank you for this model. Mine is almost finish but I have a problem with motors calibration, and I already watched your video that talk about problems and question, so sorry. First when I connect battery, one of motor boot immediatly, even if calibrating not done. I send "c+" command bluetooth to stop it and calibrate then "c-". When c- is sent another motor, 2 motors turn. it turns like fan, not one way and other way (for me at this moment, motors souldn't turn I think). I made the cube exactely in the same way like you and respected all the angles (motors, edges, sensor MPU6050), nevertheless my values are very different than you. As it was not possible to calibrate with your values, I change the part of the code where we can see "first edge between -10 and -20, etc." I tried another sensor, same values. My results are these by bluetooth terminal : calibrating on X: 0.39 Y: 24.70 Third edge OK. calibrating on X: -31.67 Y: -31.51 Second edge OK. calibrating on X: 31.37 Y: -31.02 First edge OK. calibrating on X: -0.43 Y: -11.97 Vertex OK. Calibration seems to be OK with these values, but why motors are turning fast without reverse, and why on a edge there are always two motors turning instead of only one ? I verified wires 1 to 8. first side, two motors turn, second side, two motors turn, third side, all motors turn. Have you an idea ? I use an ESP32 D1 MINI (also with wroom32). I compared GPIO to be sure that same input/output are OK, PWM, etc. I specify that with the "test_motors.ino" the motors rotate slowly in one direction then in the other, and one after the other,so connection OK. Other thing, I used a buzzer seems to be the same as you but impossible to hear song, only a little slam membrane. To fix it I had to modify beep() function like that (a digitalwrite don't make song, mine wants a frequency) : void beep() { tone(BUZZER, 1000); // Send 1KHz sound signal... delay(70); // ...for 1 sec noTone(BUZZER); // Stop sound... delay(80); } Thank you a lot 🙏I love this project and I hope to show it to you in a few time ☺

I do c+, wait on balance point; then "c-", motor turns until I do another "c+" or put the cube on a face. On your video you can turn on another edge without turning.

I have the wheel running, not on same stick as yours, but a modified stick mounted like a frame on table, as I only got Arduino Uno and old motor driver. MPU works, I use optical incremental encoder with code to produce rad/sec with direction. PID works, can see the right flow when plotted, also swings to other side when I push it. So far so good. But, doesn't hold the balance :(. It tries to aggressively balance. Keeps trying forever if i force stick to stay within 6 degree threshold with supports on side. But if I let go of supports, the stick falls to ground. Center of gravity issue? Any clues.?

Hello, I wanted to reach out to express my admiration for your project - it's truly impressive! As I'm working on a similar project myself, I stumbled upon yours. After delving into your code, I have a few questions that I'm hoping you can help me with. Firstly, I noticed that your regulator operates every 10 milliseconds, is that correct? If so, it raises the question of whether the Nidec 24H motor must respond even faster than this 10 ms interval, am I correct in assuming that? So where did you find data about this motor?

Gotta figure out why reaction latency is high.

The reaction wheel rotates at a precisely selected speed. Then is braked suddenly. As the triangle rotates (falling), the angle is measured and when the balancing point is reached, balancing is activated. The selection of the rotation speed and the measurement of the angle require very precise alignment.
